APPLICABILITY:

SUBJECT:
Reprogramming File Availability for Hard Starting in
Sub-Freezing Temperatures, DTC P0400 and Surging in High Altitudes
NUMBER: 11-200-20R
DATE: 02/13/20
REVISED: 05/06/20
INTRODUCTION:
This bulletin announces the availability of reprogramming files to optimize the Engine Control
Module (ECM). The new logic will address customer concerns of:
•
Hard starting in sub-freezing (below 32 degrees Fahrenheit) conditions: Main Relay contacts
may freeze in an “open” condition when turning the engine off after a short trip then
attempting to restart.
•
Check Engine light illumination with a DTC P0400 stored in memory: ECM may test the
EGR system in error when ambient / intake air temperatures are below freezing.
•
Surging / vibration condition when using the cruise control in high-altitude areas
(FORESTER ONLY): Incorrect amount of throttle compensation when EGR is switched on
or off.
Operation of the self-shut relay has been changed to minimize the temperature difference inside
the relay to prevent condensation / moisture (which may freeze) from occurring. The EGR system
parameters have been changed to prevent testing when ambient temperatures do not meet specified
criteria. Throttle control software has been optimized to prevent the surging condition.
PRODUCTION CHANGE INFORMATION:
The new logic was incorporated into Crosstrek production starting with VIN LH225898. This
bulletin will be revised with the starting VINs for the other applicable models as they become
available.

RESULT IN SERIOUS INJURY TO THOSE PERSONS OR TO OTHERS.

Service Bulletin applies to your vehicle, or that your vehicle will have that condition.
